When Uneven Color Issue Occurs

Light Choke Cleaning

Note: Light choke cleaning consumes a large quantity of ink. Frequently performing light choke
cleaning makes the print heads more likely to be damaged. Avoid using it more than necessary.
Perform the light choke cleaning when color is uneven and unstable, i.e. darkness or brightness
is different though the same data is printed with the same settings. To obtain stabilized color
output, stir the ink.
